Description
PRIORITY
[0001] This application claims priority under 35 U.S.C.
.sctn.119(a) to Korean Patent Application Serial No.
10-2016-0023548, which was filed in the Korean Intellectual
Property Office on Feb. 26, 2016, the entire disclosure of which is
incorporated herein by reference.
BACKGROUND
[0002] 1. Field of the Disclosure
[0003] The present disclosure relates generally to an antenna of an
electronic device including a display.
[0004] 2. Description of the Related Art
[0005] An electronic device, e.g., a smartphone or a tablet,
supporting wireless communication includes an antenna. The
electronic device may transmit and receive signals of a specific
frequency band using a metallic body disposed within the electronic
device or defming an external appearance of the electronic device
as a radiator.
[0006] For an operation of the antenna, a metallic body may be used
as a ground area of the antenna, in addition to being used as the
radiator. A ground layer in a substrate of the electronic device
may also correspond to a ground area of the antenna.
[0007] The electronic device may include a display panel for a
display. When a display function is implemented, noise may occur in
a display driving circuit, such as a display driving integrated
chip (DDIC). Therefore, in order to prevent the noise from
interfering with the operations of the internal parts of the
electronic device, a shielding metal sheet may be disposed on a
rear surface of the display panel.
[0008] However, when an entire front surface of the electronic
device is implemented as a display, the radiation performance of
the antenna may be degraded by the shielding metal sheet. For
example, because the electronic device in which the display does
not cover the entire front surface thereof may use an existing side
metal frame as an antenna radiator and provide marginal spaces at
upper and lower ends thereof, the radiation using the metal frames
located at the upper and lower ends is hardly influenced. However,
in an electronic device in which the display covers the entire
front surface thereof, such that marginal spaces are not provided
at upper and lower ends thereof, the radiation performance of the
antenna may be lowered by the display (or a conductive material
such as a rear metal sheet of the display).
SUMMARY
[0009] The present disclosure is made to address at least the
above-mentioned problems and/or disadvantages and to provide at
least the advantages described below.
[0010] Accordingly, an aspect of the present disclosure is to
provide an electronic device that utilizes a front display
structure as an antenna element, wherein an entire front surface of

housing and exposed through the first plate, a first conductive
plate attached to the display or integrated into the display,
wherein the first conductive plate faces the first direction and
includes a first periphery extending along the side plate, a second
conductive plate facing the third direction. The second conducive
plate includes a second periphery extending along the first
periphery and a portion of the second periphery is coupled to the
first periphery, and a wireless communication circuit electrically
connected to the second conductive plate, wherein the wireless
communication circuit is configured to use at least one of the
first conductive plate and the second conductive plate as an
antenna element.

DETAILED DESCRIPTION
[0032] Hereinafter, various embodiments of the present disclosure
will be described with reference to the accompanying drawings.
Accordingly, those of ordinary skill in the art will recognize that
modification, equivalent, and/or alternative on the various
embodiments described herein can be variously made without
departing from the scope and spirit of the present disclosure. With
regard to description of drawings, similar components, elements,
features, and structures may be marked by similar reference
numerals.
[0033] FIG. 1 illustrates an electronic device according to an
embodiment of the present disclosure.
[0034] Referring to FIG. 1, the electronic device 100, e.g., a
smartphone, a tablet, etc., has a parallelepiped shape with a
specific volume or a shape that is similar to a parallelepiped
shape. Although the front surface and the rear surface of the
electronic device 100 are implemented by flat planar surfaces, all
or some (e.g., two side left and right surfaces) of the four side
surfaces of the electronic device 100 may be implemented to have a
specific curvature to improve a grip feeling.
[0035] The housing, which constitutes an external appearance of the
electronic device 100, may be classified into a front surface, a
rear surface, and side surfaces. For example, the housing of the
electronic device 100 may include a first plate facing a first
direction (a front surface, +z direction), a second plate facing a
second direction (a rear surface, -z direction) that is opposite to
the first direction, and a side plate facing a third direction (a
side surface, .+-.x or .+-.y direction) that is perpendicular to
the first direction (or the second to direction) or substantially
perpendicular to the first direction (or the second direction). The
side plate may surround a space between the first plate and the
second plate. The side plate, for example, may be implemented to be
planar or curved.
[0036] Each of the first, second, and third plates may correspond
to one component or a group of components. For example, the first
plate may correspond to a glass cover, the second plate may
correspond to an injection-molded ring or one or more side metal
frames classified by insulation members, and the third plate may
correspond to a rear cover. Alternatively, one or more components
may constitute each of the first, second, and third plates, or one
component may be disposed in two or more areas of each of the
first, second, and third plates. Accordingly, in the present
disclosure, the terms of a first plate, a second plate, and a third
plate are not to be construed such that one plate corresponds only
to one element.
[0037] In FIG. 1, the electronic device 100 includes a cover window
110 and a rear case 170. The cover window 110 may be bent from one
surface of the electronic device 100. For example, the cover window
110 is bent from a periphery of an upper surface or a lower surface
of the electronic device 100. The cover window 110 and the rear
surface case 170 define a front surface (e.g., the first plate) and
a rear surface (e.g., the second plate) of the electronic device
100, respectively.
[0038] Alternatively, the cover window 110 may be bent from a left
side surface, a right side surface, or at least one of a plurality
of surfaces defining an external shape of the electronic device
100, or the cover window 110 may be disposed only on a front
surface of the electronic device 100.
[0039] A portion of the rear case 170 is expanded to a side surface
of the electronic device 100. As illustrated in FIG. 1, the rear
case 170 constitutes the left and right side plates of the
electronic device 100. The remaining part of the rear case 170,
except for an area of the rear case 170 corresponding to the left
and right side plates of the electronic device 100, or an area of
the rear case 170 corresponding to upper and lower side plates of
the electronic device 100, may be implemented by an insulation
material such as plastic.
[0040] Alternatively, a portion of the rear case 170 may constitute
a portion of upper and/or lower side plates of the electronic
device 100. An area of the rear case 170 corresponding to the upper
and lower side plates may be implemented by a conductive material,
such as a metal frame. The metal frame may be operated as an
antenna radiator. However, the entire rear case 170 may be
implemented by plastic or metal.
[0041] In FIG. 1, the upper and lower side plates of the electronic
device 100 are formed by the cover window 110 and the rear case
170. However, as an alternative, a side plate may be formed by only
the rear case 170 or by only the cover window 110.
[0042] The electronic device 100 may be designed such that at least
one of corner areas 10 radiate electromagnetic waves for wireless
communication. For example, a conductive plate 130, such as a
copper (Cu) sheet, which is integrated into the display panel or
attached to the display panel, may have a structure of a
leftward/rightward slot while being bent at a location
corresponding to the corner area 10.
[0043] As illustrated in FIG. 2A, the conductive plate 130 may
include a first conductive plate 131 and a second conductive plate
132. The first conductive plate 131 may face a front surface (a
first direction) like the cover window 110, and the second
conductive plate may face a side surface (a third direction, +y
direction) like the lower side plate.
[0044] The first conductive plate 131 may include a first periphery
extending along the lower side plate, and the second conductive
plate 132 may include a second periphery extending along the first
periphery. A portion of the second periphery may be coupled to the
first periphery, such that two slots may be defined in one corner
by the first periphery, the second periphery, and a connection
area. Alternatively, one slot or three or more slots may be formed
in one corner by varying the locations, the sizes, and the number
of the connection areas.
[0045] An FPCB 140 is disposed under the conductive plate 130. The
conductive plate 130 may be electrically connected to a wireless
communication circuit through the FPCB 140. For example, when the
wireless communication circuit supplies electric power to the
second conductive plate 132 through the FPCB 140, at least a
portion of the first conductive plate 131 and/or the second
conductive plate 132 may be used as an antenna element. For
example, if electric power is supplied at one point of the FPCB
140, the electronic device 100 may transmit and receive signals of
a specific frequency band, based on an electrical path defined by
the second conductive plate 132, the connection area, and the first
conductive plate 131. According to the lengths of the slots defined
by the first periphery, the second periphery, and the connection
area, the electronic device 100 may transmit and receive signals of
different frequency bands, based on the slots.
[0046] FIG. 2A is an exploded perspective view of the electronic
device illustrated in FIG. 1.
[0047] Referring to FIG. 2A, a display panel 120 is disposed under
the front cover window 110 of the electronic device 100. The
display panel 120 has a shape corresponding to the cover window
110. For example, the display panel 120 may be implemented by a
flexible (or deformable) display panel for a shape corresponding to
the cover window 110. When the cover window 110 defines at least a
portion (e.g., an upper surface and a lower surface) of a side
housing of the electronic device 100 and a front housing, the
display panel 120 may also include a front display area and areas
expanded to upper and lower ends thereof, as illustrated in FIG.
2A. The areas expanded to the upper and lower ends of the display
panel 120 may include an area for display. Alternatively, the
display panel 120 may include an area that may be displayed only on
a front surface thereof, and upper and lower ends of the display
panel 120 may correspond to non-display areas, such as black
matrices.
[0048] The display panel 120 may include a plurality of layers. For
example, when the display panel 120 corresponds to an organic light
emitting diode (OLED), it may include a thin film transistor
(TFT)/OLED layer, an encapsulation glass layer, and a polarizer.
When the display panel 120 corresponds to a liquid crystal display
(LCD), it may sequentially include a back light unit (BLU), a
polarizer, glass, a TFT/electrode layer, a liquid crystal, a color
filter, and a polarizer. When the display panel 120 supports a
touch function, a touch panel may be additionally provided. The
display panel 120 may also referred to as a display 120.
[0049] The conductive plate 130 (e.g., a copper sheet) implemented
by a conductive member for blocking noise that occurs when the
display panel 120 is driven is disposed under the display panel
120. A planar surface of the conductive plate 130 may be attached
to the display panel 120 or may be integrated into the display
panel 120. Further, the conductive plate 130 may have a shape that
is the same as or similar to that of the display panel 120. For
example, when the display panel 120 is bent at upper and lower ends
thereof and a front area and upper end/lower end areas thereof are
physically connected to each other as illustrated in FIG. 2A, the
conductive plate 130 may also include a first conductive plate 131
corresponding to the front area, a second conductive plate 132
corresponding to the lower end area, and a third conductive plate
corresponding to the upper end area.
[0050] The conductive plates corresponding to the areas may be
connected to each other by a connection area having a specific
width. The connection area may provide an electrical path facing a
ground area GND when the second conductive plate 132 is used as a
portion of an antenna radiator or an antenna element.
Alternatively, the areas corresponding to the conductive plate 130
may not be physically connected to each other, and a plurality of
physically spaced areas may be included in the conductive plate
130. In this case, the separated areas may be electrically
connected to each other by an electrical path provided by the FPCB
140 disposed under the conductive plate 130.
[0051] The conductive plate 130 may have a front area and at least
one side area. For example, the conductive plate 130 may include a
first conductive plate 131 disposed parallel to the first plate of
the electronic device 100 or the front surface of the display panel
120, a connection area bent while extending only at a portion of
the periphery of the first conductive plate 131, and a second
conductive plate 132 physically and electrically connected to the
first conductive plate 131 by the connection area.
[0052] The first conductive plate 131 and the second conductive
plate 132 may define a specific angle, e.g., 90 degrees, and in
this case, the second conductive plate 132 may be disposed
substantially parallel to the side surface of the electronic device
100. Alternatively, the electronic device 100 may include a side
display having a specific inclination (e.g., 30 degrees), the
second conductive plate 132 may be disposed parallel to the side
display, i.e., may be disposed to define the specific angle (i.e.,
30 degrees) together with the first conductive plate 131.
Hereinafter, unless not specifically mentioned, it will be assumed
that the first conductive plate 131 and the second conductive plate
132 of the conductive plate 130 are perpendicular to each
other.
[0053] A conductive material, such as the FPCB 140, may contact the
conductive plate 130. The FPCB 140 may include a first planar
portion facing a side surface (e.g., a third direction) and a
second planar portion facing the front surface (e.g., the first
direction). The first planar portion of the FPCB 140 may physically
and electrically contact the second conductive plate 132, and the
second planar portion may physically and/or electrically contact
the first conductive plate 131. Further, the FPCB 140 may include a
conductive line and/or a conductive pattern providing an electrical
connection between the second conductive plate 132 and the wireless
communication circuit.
[0054] For the durability and coupling stability of the antenna,
the FPCB 140 may be attached to the first conductive plate 131 and
the second conductive plate 132 of the conductive plate 130 while
contacting the first conductive plate 131 and the second conductive
plate 132 of the conductive plate 130. When the second conductive
plate 132 is used as a first antenna radiator, a metallic body
extending from at least a portion of the FPCB 140 or one point of
the FBCB 140 may be used as a second antenna radiator. For example,
an antenna radiator having an electrical path defined by the FPCB
140 and the second conductive plate 130 may be implemented. In this
case, the first conductive plate may provide a ground area for an
antenna.
[0055] The electronic device 100 may include an insulation member,
such as a bracket 150, which may provide a space, in which a
printed circuit board (PCB) of the electronic device 100, and/or an
application processor (AP), a memory, and electrical components
160, such as sensors, which are mounted on the PCB may be mounted,
and may support electrical components 160 to be fixed in place. The
shape of the bracket 150 may be variously modified based on the
structure of the electronic device 100. The bracket 150 may have an
opening or a hole in which various components are mounted or
through which a connection member is inserted. The connection
member may include a C-clip or a pogo pin for physically or
electrically connecting a substrate (e.g., the PCB) and components
(e.g., the FPCB 140) vertically or horizontally spaced apart from
the substrate.
[0056] The rear case 170 may prevent the electrical components 160
from being exposed, when the rear cover 180 is removed. For
example, when the rear cover 180 is removed from the electronic
device 100, only a battery and a SIM card may be exposed.
Alternatively, the rear case 170 and the rear cover 180 may be
integrally implemented. For example, in a smartphone, in which a
battery cannot be removed by the user, the rear case 170 and the
rear cover 180 may be integrally formed.
[0057] FIG. 2B illustrates an upper end and/or a lower end of the
electronic device illustrated in FIG. 1.
[0058] Referring to FIG. 2B, the cover window 110 extends from the
front surface of the electronic device 100 to an upper end area
and/or a lower end area of the electronic device 100. When the rear
case 170 of the electronic device 100 includes a metal, the rear
case 170 includes an insulator 174 that partitions an area of an
antenna radiator from the other areas, such that an area 175 of the
rear case may be used as the antenna radiator at an upper end area
or a lower end area of the electronic device 100. An area of the
antenna radiator distinguished from the other areas by the
insulator 174 may be used to transmit and receive a signal of a
targeted frequency band. As the targeted frequency band changes,
the insulator 174 may be disposed at a location that is different
from that of FIG. 2B.
[0059] Although FIG. 2B illustrates a metal frame that constitutes
a housing of an upper end or a lower end of the electronic device
100 and is used as an antenna radiator, the cover window 110 may
extend to the left and right side surfaces of the electronic device
100. In this case, similarly to the above-mentioned example, metal
areas of the left and right side surfaces, which are partitioned by
insulator 174, may be utilized as antenna radiators.
[0060] FIG. 2C illustrates a sectional view and an exploded
perspective view of the electronic device illustrated in FIG.
1.
[0061] Referring to FIG. 2C, the cover window 110 defines a front
surface and portions of side surfaces of the electronic device 100.
The display panel 120 attaches to the cover window 110 and is
disposed on the front surface and the side surfaces of the
electronic device 100. The conductive plate 130 is disposed under
the display panel 120.
[0062] More specifically, the first conductive plate 131 is
attached to an area corresponding to the front surface of the
display panel 120, and the second conductive plate 132 is attached
to an area corresponding to a side surface of the display panel
120. When the first conductive plate 131 and the second conductive
plate 132 are physically separated from each other, two or more
conductive plates are disposed under the display panel 120. If the
second conductive plate 132 is bent at one end of the first
conductive plate 131, one conductive plate 130 may be disposed
under the display panel 120.
[0063] The first conductive plate 131 and the second conductive
plate 132 may be bonded to the FPCB 140, e.g., using a conductive
tape interposed between the first conductive plate 131 and/or the
second conductive plate 132, and the FPCB 140.
[0064] The FPCB 140 may be connected to the electrical components
160. For example, the bracket 150 may be disposed between the FPCB
140 and the electrical components 160, and the FPCB 140 and the
electrical components 160 may be electrically connected to each
other through a connection member located in a hole provided in the
bracket 150. A portion of the FPCB 140 may be disposed between a
side wall or a side surface of the bracket 150 and the second
conductive plate 132. For example, when the FPCB 140 includes a
first planar portion coupled to the first conductive plate 131 and
a second planar portion coupled to the second conductive plate 132,
the second planar portion may be disposed between a side wall of
the bracket 150 and the second conductive plate 132. Further, the
side wall of the bracket 150 and the second planar portion of the
FPCB 140 may be spaced apart from each other by a specific gap.
[0065] The communication circuit (e.g., a communication processor
(CP) or a radio frequency (RF) module) may be electrically
connected to the FPCB 140 and the second conductive plate 132. The
communication circuit may feed electric power to the electrical
path defined by the FPCB 140 and the second conductive plate 132.
The first conductive plate 131 connected to the FPCB 140 or
connected to at least one point of the second conductive plate 132
may be utilized as a ground area of the antenna. Accordingly, the
electronic device 100 may stably receive a signal of a targeted
frequency band by using the second conductive plate 132 and the
FPCB 140 as an antenna radiator and using the wide ground area of
the first conductive plate 131.
[0066] A non-display area may be located at a corner portion
(curved portion) of the display panel 120. For example, a
non-display area in which a driving circuit unit for driving the
display panel 120, a backlight lamp, and black matrices are
disposed may be disposed from a corner portion to a side surface
area extending from the corner portion. All of the corner and side
surface areas (a second panel area) of the display panel 120,
except for a backlight unit (BLU) for outputting a color or a first
panel area in which content is output, may correspond to a
non-display area. The display panel 120 may be divided into a first
panel area corresponding to the front surface of the electronic
device and a second panel area corresponding to a side surface of
the electronic device or corresponding to the remaining area,
except for the first panel area. Content may be output from the
first panel area and the second panel area may correspond to a
non-display area.
[0067] If the corner portion of the display panel 120 corresponds
to a non-display area, electromagnetic waves may be smoothly
radiated by the slot structure of the conductive plate 130 located
under the corner portion of the display panel 120. For example,
electromagnetic waves may be radiated through the corner area 10 by
the slot structure defined by the first conductive plate 131, the
second conductive plate 132, and the connection area connecting the
first conductive plate 131 and the second conductive plate 132.
[0068] Alternatively, the non-display area may be formed under the
corner portion, i.e., in a side area. That is, the first panel area
of the display panel 120, in which content is output, may extend to
the front surface and an area of a side surface of the electronic
device 100. In this case, electromagnetic waves may be radiated
through the slot structure, by expanding the first conductive plate
131 such that the first conductive plate 131 corresponds to the
first panel area and moving the slot structure to a location
corresponding to the non-display area (e.g., the second panel area)
formed in the side surface area.
[0069] FIGS. 3A to 3D illustrate different examples of a conductive
plate according to various embodiments of the present
disclosure.
[0070] As described above, the conductive plate is not necessarily
limited to a metal plate. For example, the conductive plate 130 may
be a conductive layer. Further, the conductive plate 130 may be
implemented by a conductive cover sheet. The conductive plate 130
may be replaced by a first conductive member, and the FPCB 140 may
be replaced by a second conductive member.
[0071] Referring to FIG. 3A, the first conductive plate 131, i.e.,
a first area 131, corresponds to the front area of the electronic
device 100. Further, the second conductive plate 132, i.e., a
second area 132, is disposed at a specific angle (e.g., 90 degrees)
to the first area 131. The first area 131 and the second area 132
may be electrically connected to each other via an FPCB.
[0072] Referring to FIG. 3B, the first area 131 and a second area
134 are connected to each other. Specifically, the second area 134
is bent from one end of the first area 131. The bent area may have
a width that is the same as that of the first area 131, or may have
a width that is smaller than that of the first area 131, as
illustrated. Further, the second area 134 may have a width
corresponding to that of the first area 131, or may have a width
that is smaller than that of the first area 131. The first area 131
and the second area 134 may have sizes and forms corresponding to a
shape of the display panel 120.
[0073] Referring to FIG. 3C, the first area 131 and a second area
135 are connected to each other at two points of the conductive
plate. In this case, the conductive plate includes a slit type
opening 136. The second area 135 may be operated as a slot antenna
or a slit antenna based on a location of the feeding provided by an
FPCB electrically contacts the conductive plate.
[0074] Referring to FIG. 3D, a second area 137 includes a pattern
for receiving a signal of one or more frequency bands. For example,
the second area 137 may include one or more branch having different
electrical path lengths. A branch having a relatively short path
may be adapted to receive a signal of a high frequency band, and a
branch having a relatively long path may be adapted to receive a
signal of a low frequency band.
[0075] Various other examples of a conductive plate may be
provided. For example, a slit antenna that is similar to that of
FIG. 3C may be implemented by coupling the first area 131 and the
second area 132 of FIG. 3A to the FPCB 140 having a suitable shape.
Further, the shapes of FIGS. 3B to 3D may be implemented directly
by the structure or shape of the conductive plate 130, or may be
implemented by the structure or shape formed through coupling of
the conductive plate 130 and the FPCB 140.
[0076] FIG. 4 illustrates an electronic device according to an
embodiment of the present disclosure. Unlike the electronic device
100 of FIG. 1, a display panel 220 (as illustrated in FIG. 5) of
the electronic device 200 of FIG. 4 does not extend to a side
surface of the electronic device 200, but covers the entire area of
the front surface.
[0077] Referring to FIG. 4, a cover window 210 and a display panel
220 are removed from the electronic device 200, for convenience of
description. The electronic device 200 includes a conductive plate
230, which includes a first conductive plate 231 located at a
central portion thereof, a second conductive plate 232 located at a
lower end thereof, a third conductive plate 233 located at an upper
end thereof, and a connection area electrically connecting the
conductive plates. The conductive plate 230 may be implemented by
one conductive sheet including a total of four slots, each of which
has an opened side, two slots being formed at each of an upper end
and a lower end of the conductive plate 230. However, as described
above, the number, the forms, and the lengths of the slot
structures formed in the conductive plate 230 may be various
modified.
[0078] When radiation of an antenna is implemented only at a lower
end of the electronic device 200, the slot structure part of an
upper end of the electronic device 200 may be replaced by a
conductor. That is, the first conductive plate 231 and the third
conductive plate 233 may be implemented by one rectangular plate
without using a slot structure at an intermediate portion
thereof.
[0079] FIG. 5 is an exploded perspective view of the electronic
device illustrated in FIG. 4. In the following description of FIG.
5, detailed descriptions of the elements that are the same as or
similar to or correspond to the above-described elements in FIG. 2A
will be omitted.
[0080] Referring to FIG. 5, the electronic device 200 includes a
front cover window 210. The cover window 210 may correspond to an
enhanced glass cover configured to protect the entire front surface
of the electronic device 200 without extending to a side surface of
the electronic device 200.
[0081] A display panel 220 is disposed under the front cover window
210. The display panel 220 may be implemented by a flat panel, like
the cover window 210. Alternatively, the display panel 220 may be
implemented by a flexible display panel in which a portion of an
upper end and/or a lower end of the display panel 220 is bent over
the side surface of the electronic device 200 to output content on
the entire front surface of the electronic device 200.
[0082] The electronic device includes a conductive plate 230
integrated into the display panel 220 or attached under the display
panel 220. For example, similarly to the conductive plate 130 of
the electronic device 100, the conductive plate 230 includes a
first conductive plate 231 corresponding to a central area thereof,
a second conductive plate 232 corresponding to a lower end area
thereof, and a third conductive plate 233 corresponding to an upper
end area thereof. The conductive plates 231 to 233 corresponding to
the areas may be connected to each other by a connection area
having a specific width.
[0083] Unlike the conductive plate 130 of the electronic device
100, the conductive plate 230 may have plates on the same plane.
Accordingly, unlike in the electronic device 100 in which a
substrate disposed under the conductive plate 130 is implemented by
the FPCB 140, the substrate disposed under the conductive plate 230
may be implemented by a general PCB, as well as an FPCB.
Hereinafter, it will be assumed that the FPCB 240 is disposed under
the conductive plate 230.
[0084] The electronic device 200 includes an insulation member,
i.e., a bracket 250. The bracket 250 provides a space in which a
battery 251, a first PCB 261, a second PCB 262, or other electrical
components, such as sensors and parts, which are mounted on a PCB,
and may function to support the electrical components such that the
electrical components, are fixed in place.
[0085] The rear case 270 may prevent electrical components from
being exposed when the rear cover 280 is removed. Alternatively,
the rear case 270 and the rear cover 280 may be integrally
implemented.
[0086] FIG. 6 illustrates a sectional view and an exploded
perspective view of the electronic device illustrated in FIG. 4.
The elements and description of FIG. 6, which are the same as,
similar to, or correspond to the above-described elements and
description of FIG. 3, will be omitted.
[0087] Referring to FIG. 6, the cover window 210 may define a front
surface of the electronic device 200. The display panel 220 is
disposed under the cover window 210. The conductive plate 230 is
disposed under the display panel 220.
[0088] The first conductive plate 231 and the second conductive
plate 232 may be bonded to the FPCB 240. As illustrated in FIG. 6,
because the FPCB 240 does not need to have a flexible property,
i.e., because it is flat, it may be replaced by another material
such as a planar PCB.
[0089] The FPCB 240 may be connected to the first PCB 261 and/or
the second PCB 262. For example, the FPCB 240 and the PCBs 261 and
262 may be electrically connected to each other through a
connection member located in a hole provided in the bracket
250.
[0090] The display panel 220 may be divided into a plurality of
areas to correspond to the structure of the conductive plate 230
disposed under the display panel 220. For example, the display
panel 220 may be logically divided into a first panel area, a
second panel area, and a third panel area.
[0091] The first panel area, for example, may correspond to a
central area of the display panel 220 corresponding to the first
conductive plate 231. The first panel area may output an execution
screen (e.g., an image, a video, a webpage, or a game screen) of a
main application. The first panel area may have a first width and a
first height. The first width and the first height may satisfy a
specific ratio, e.g., a screen ratio of 16:9.
[0092] The second panel area may correspond to a lower end area of
the display panel 220 corresponding to the second conductive plate
232. The second panel area may output a status bar, a notification
bar, a quick menu, and/or a control menu of an application executed
in the first panel area. The second panel area may have a first
width that is the same as that of the first panel area and a second
height that is shorter than that of the first panel area.
Similarly, the third panel area may have a first width, and a
second height or a third height that is slightly longer or shorter
than the second height. Alternatively, the third panel area may be
omitted. Further, the display panel 220 may further include a
logically divided fourth panel area or additional panel areas.
[0093] The first panel area and the second panel area may be spaced
apart from each other by a gap. The location of the gap may
correspond to the location of the slot structure of the conductive
plate 230. That is, the first panel area and the second panel area
may be spaced apart from each other by a gap between a periphery of
the first conductive plate 231 and a periphery of the second
conductive plate 232, or a gap that is slightly larger or smaller
than the gap between the periphery of the first conductive plate
231 and the periphery of the second conductive plate 232.
[0094] The above-described spacing between the panel areas does not
necessarily mean physical separation of the display panel 220.
[0095] The driving circuit configured to drive the display panel
220 may not output content in an area corresponding to the gap,
that is, in a thin area of the display panel 220 corresponding to
the spacing between the first panel area and the second panel area.
For example, the pixel density of the area of the display panel 220
corresponding to the gap may be set to be lower than the pixel area
of the first panel area or the second panel area of the display
panel 220. The driving circuit may be disposed such that a BLU of
the area corresponding to the gap is always turned off to be viewed
in black, or only a black matrix may be disposed in the gap without
using a BLU. The implementation of the display panel 220 may
prevent the radiation performance of the antenna from being lowered
by the display panel 220 or an output signal provided to the
display panel 220 from being distorted by the radiation of the
antenna.
[0096] The first panel area and the second panel area may be
physically spaced apart from each other by a specific space.
[0097] FIG. 7 illustrates an electronic device according to an
embodiment of the present disclosure.
[0098] Referring to FIG. 7, a cover window 310 is removed from an
electronic device 300, for convenience of description. The overall
configuration of the electronic device 300 is similar to that of
the electronic device 200, but unlike the electronic device 200
having only the display panel 220, the electronic device 300
includes a first display panel 321, a second display panel 322, and
a third display panel 323, i.e., three physically divided display
panels. The first display panel 321 may have a specific screen
ratio (e.g., 16:9), and may correspond to a main display area, on
which an execution screen of an application is displayed. The
display panels of the electronic device 300 may be generally
referenced by the display panel 320 (see FIG. 8). The display panel
320 includes a first panel area, a second panel area, and a third
panel area corresponding to the first display panel 321, the second
display panel 322, and the third display panel 323,
respectively.
[0099] In order to drive the first display panel 321, the second
display panel 322, and the third display panel 323, the electronic
device 300 may include a first display driving circuit
corresponding to the first panel area, and a second display driving
circuit corresponding to the second panel area. The driving
circuits may be electrically connected to the panel areas (the
first display panel 321, the second display panel 322, and the
third display panel 323), respectively. For example, the first
display driving circuit may output an application execution screen
on the first display panel 321, and the second display driving
circuit may output specific screens, e.g., a notification bar, a
status bar, and a quick menu, on the second display panel 322.
[0100] When the second panel area, i.e., the area corresponding to
the second display panel 322 corresponds to a non-display area,
such as a black matrix (or when a display is not implemented in the
second panel area), a conductive plate (e.g., the second conductive
plate 232) may be disposed in the non-display area. In this case,
the wireless communication circuit may be electrically connected to
the conductive plate through an FPCB, and an antenna configured to
transmit and receive a signal of a frequency band corresponding to
the electrical path formed by the connection may be implemented.
When the third panel area or the whole part or a portion of the
second panel area and the third panel area, as well as the second
panel area correspond to a non-display area, a conductive plate may
be disposed at a portion corresponding to the non-display area so
that an antenna may be implemented.
[0101] FIG. 8 illustrates display panels and a metal plate of the
electronic device illustrated in FIG. 7.
[0102] Referring to FIG. 8, the first display 321 and the second
display panel 322 of the electronic device 300 may be spaced apart
from each other by a specific space. The location of the gap may
correspond to the location of the slot structure of the conductive
plate 330. That is, the first display panel 321 and the second
display panel 322 may be spaced apart from each other by a gap
between a periphery of the first conductive plate 331 and a
periphery of the second conductive plate 332, or a gap that is
slightly larger or smaller than the gap between the periphery of
the first conductive plate 331 and the periphery of the second
conductive plate 332.
[0103] The space generated by the spacing between the display
panels may prevent the radiation performance of the antenna from
being lowered or an output signal provided to the display panel 320
from being distorted by the radiation of the antenna.
[0104] FIG. 9 illustrates an electronic device including a
3-surface display according to an embodiment of the present
disclosure.
[0105] Referring to FIG. 9, the electronic device 400 includes a
three-surface display corresponding to a front surface, an upper
end surface, and a lower end surface thereof. For example, the
electronic device 400 may include one flexible display panel bent
at upper end and lower end corners of the electronic device 400, or
may include three display panels (e.g., a first display panel 421,
a second display panel 422, and a third display panel 423) that are
physical divided.
[0106] A conductive plate may be disposed under the display
panel(s). The conductive plate may include a first conductive plate
431, a second conductive plate 432, and a third conductive plate
433, and may have opened slot structures in the corner areas
thereof.
[0107] An electronic device having a vertically expanded display,
like the electronic device 400, may include an antenna using a
non-conductive area between the front surface, and upper/lower end
side surface display. The upper/lower end side surface conductive
plate 432/433 utilized as an antenna radiator may be electrically
connected to the front surface conductive plate 431. For example,
feeding units may be constituted in the slot areas, i.e., the
non-conductive areas by using the FPCB, and an antenna based on the
electrical path formed around the slots may be implemented by
feeding an RF signal to the conductive plate 432/433.
[0108] FIG. 10 illustrates an antenna including a 3-surface display
according to an embodiment of the present disclosure.
[0109] Referring to FIG. 10, electric power may be provided to the
second conductive plate 432 in the non-conductive area (slot area)
between the first conductive plate 431 and the second conductive
plate 432. For example, electric power may be provided to the
second conductive plate 432 by the FPCB disposed under the
conductive plate 431 one or more times.
[0110] The electronic device 400 may also utilize an additional
antenna radiator, as well as the second conductive plate 432. For
example, the electronic device 400 may transmit and receive a
signal of an additional frequency band through a first radiator
1010 electrically connected to the second conductive plate. The
first radiator 1010 may be embodied as a metal frame constituting a
portion of a side housing of the electronic device 400. Further,
the electronic device 400 may transmit and receive a signal of an
additional frequency band through a second radiator 1020 extending
from a feeding path provided in the FPCB.
[0111] Further, a lumped element, such as a capacitor or an
inductor, may be added between the first conductive plate 431 and
the second conductive plate 432. For example, the length of an
electrical path formed by the antenna structure of FIG. 10 may be
made smaller by disposing a variable capacitor 1030 between the
first conductive plate 431 and the second conductive plate 432. In
contrast, the length of the electrical path may be made larger by
disposing an inductor.
[0112] FIG. 11A illustrates an electronic device including a
5-surface display according to an embodiment of the present
disclosure.
[0113] Referring to FIG. 11A, the electronic device 500 includes a
five-surface display, i.e., a front surface and four side surfaces.
For example, the electronic device 500 may include one flexible
display panel bent at upper and lower end corners of the electronic
device 500 and two separate display panels attached to side
surfaces thereof, or may include five physically divided display
panels (e.g., a first display panel 521, a second display panel
522, a third display panel 523, a fourth display panel 524, and a
fifth display panel 525).
[0114] A conductive plate 530 may be disposed under the display
panel(s). The conductive plate 530 may include a first conductive
plate 531, a second conductive plate 532, a third conductive plate
533, a fourth conductive plate 534, and a fifth conductive plate
535, and may have opened slot structures in the corner areas
thereof in a manner that is similar to the above-mentioned
manner.
[0115] When the display extends leftwards and rightwards and
upwards and downwards, as in the electronic device 500, an antenna
may be constituted as described above. For example, an antenna may
be constituted by utilizing a non-conductive area between the front
surface and any one of the side displays. In this case, an antenna
using a total of eight slots may be implemented.
[0116] The conductive plate 530 may have a structure that is not
deflected from one side surface towards another side surface of the
electronic device 500. For example, any one of the conductive
plates 532, 533, 534, and 535 formed by extending the first
conductive plate 531 to the four side surfaces may extend to
another adjacent side surface. For example, the fourth conductive
plate 534 may extend towards the third conductive plate 533. In
this case, the length of the third conductive plate 533 may be
smaller than that of FIG. 11. Through the modification, the
electronic device 500 may receive a signal of a low frequency band
by using the lengthened fourth conductive plate 534 and may receive
a signal of a high frequency band by using the shortened third
conductive plate 533.
[0117] FIG. 11B illustrates an antenna structure of an electronic
device including a plurality of side displays according to an
embodiment of the present disclosure.
[0118] The electronic device 600 of FIG. 11B may have a
configuration corresponding to the electronic device 500 of FIG.
11A. The front display panel 620 and the side display panels 621,
622, 623, and 624 of the electronic device 600 may correspond to
the front display panel 521 and the side display panels 522, 523,
524, and 525 of the electronic device 500. Accordingly, the details
that correspond to or are the same as or similar to those of FIG.
11A will be omitted below.
[0119] Referring to FIG. 11B, a conductive plate 630 is disposed
under the display panels. The conductive plate 630 may be one
conductive plate curved at the four sides thereof, and may include
five conductive panels separately provided at the sides
thereof.
[0120] The conductive plate 630 may have a structure curved form
one surface to another surface thereof. For example, the conductive
plate, which extends from the metal planar portion arranged under
the front display panel 620 to the four sides, may extend to an
adjacent another side. For example, the conductive plate area 632
formed at a location corresponding to the side display panel 632
may extend in the direction of another side display panel 623.
Similarly, the conductive plate area 633 formed at a location
corresponding to the side display panel 635 may also extend in the
direction of the side display panel 623. In this case, the length
of the conductive plate area 631 corresponding to the side display
panel 623 may be smaller than that of the embodiment of FIG. 9.
Through the modification, the electronic device 600 may receive a
signal of a low frequency band by using the conductive plate area
632 or the conductive plate area 633, and may receive a signal of a
high frequency band by using the conductive plate area 631. In this
case, the planar conductive plate disposed under the display panel
620 may function as a ground area of the antenna.
[0121] FIG. 12 illustrates an antenna structure of an electronic
device including a 5-surface display according to an embodiment of
the present disclosure.
[0122] Referring to FIG. 12, electric power may be provided to the
second conductive plate 532 in the non-conductive area (slot area)
between the first conductive plate 531 and the second conductive
plate 532. Electric power may be provided to the fifth conductive
plate 535. For example, electric power may be provided to the
second conductive plate 532 and the fifth conductive plate 535 by
the FPCB disposed under the conductive plate 531 one or more times.
Although separate electric power is not fed to the fourth
conductive plate 534 in the example of FIG. 12, electric power may
be indirectly fed (coupling feeding) to the fourth conductive plate
534 or may be fed to the fourth conductive plate 534 in another
embodiment.
[0123] The electronic device 500 may utilize an additional antenna
radiator, similar to that of FIG. 10. For example, the electronic
device 500 may transmit and receive signals of an additional
frequency band through a first radiator 1210 electrically connected
to the second conductive plate 532. Further, the electronic device
500 may transmit and receive signals of an additional frequency
band through a second radiator 1220 extending from a feeding path
provided in the FPCB.
[0124] Further, a lumped element, such as a capacitor or an
inductor, may be added between the first conductive plate 531 and
the second conductive plate 532. For example, an electrical path
formed by the antenna structure of FIG. 12 may be made shorter by
disposing a variable capacitor 1230 between the first conductive
plate 531 and the second conductive plate 532. The variable
capacitor 1230 may be disposed in the FPCB 140 as in the exemplary
FPCB 140 of FIG. 13. When the FPCB 140 in which the variable
capacitor 1230 is disposed electrically connects the first
conductive plate 531 and the second conductive plate 532, the
variable capacitor 1230 may be disposed between one point of the
first conductive plate 531 and one point of the second conductive
plate 532 so that the first conductive plate 531 and the second
conductive plate 532 may be electrically connected to each other. A
command to control an element value of the variable capacitor 1230
may be delivered to the variable capacitor 1230 through a circuit
line provided on a surface or in the interior of the FPCB 140.
[0125] FIG. 13 conceptually illustrates an FPCB connected to a
conductive plate according to an embodiment. For example, the FPCB
140 as illustrated in FIG. 2A may be bent to have a suitable shape
for coupling the first conductive plate 131 and the second
conductive plate 132 of the electronic device 100 and to be coupled
to other components. Further, the FPCB 140 may be applied to the
electronic device 200, the electronic device 300, the electronic
device 400, and the electronic device 500, in addition to the
electronic device 100, to which the technical spirit of the present
disclosure may be applied, directly or after being modified.
[0126] Referring to FIG. 13, the FPCB 140 includes an RF
transmitter/receiver circuit coupling area 141. A feeding path from
an AP or a CP located on the PCB may be connected to the RF
transmitter/receiver circuit coupling area 141 of the FPCB 140
through a connection member or the like. Electric power may be fed
to the second conductive plate 132 through the feeding line 147,
such as a conductive line or a conductive patter, which extends
from the RF transmitter/receiver circuit coupling area 141.
[0127] The FPCB 140 may include an exposure area 143 for grounding.
A plurality of exposure areas 143 may be provided, and at least
some of the plurality of exposure areas 143 may be connected to the
first conductive plate 131.
[0128] Another surface of the FPCB 140 may be implemented by a
non-conductive area 149.
[0129] FIG. 14 illustrates an electronic device in a network
environment according to an embodiment of the present disclosure.
For example, the electronic device of FIG. 14 may correspond to the
electronic device 100, 200, 300, 400, or 500.
[0130] Referring to FIG. 14, the electronic device 1401, an
electronic device 1402, an electronic device 1404, and a server
1406 are connected to each other through a network 1462 and/or a
short range communication 1464. The electronic device 1401 includes
a bus 1410, a processor 1420, a memory 1430, an input/output
interface 1450, a display 1460, and a communication interface 1470.
Alternatively, the electronic device 1401 may exclude at least one
of the elements or may additionally include another element.
[0131] The bus 1410 may include a circuit that connects the
components 1410 to 1470 and transfers communications (e.g., control
messages and/or data) between the components.
[0132] The processor 1420 may include one or more of a central
processing unit (CPU), an AP, or a CP. The processor 1420 may
execute operations or data processing related to the control and/or
communication of at least one other component of the electronic
device 1401.
[0133] The memory 1430 may include a volatile and/or nonvolatile
memory. The memory 1430 may store a command or data related to at
least one other component of the electronic device 1401. The memory
1430 may store software and/or a program 1440. The program 1440
includes a kernel 1441, middleware 1443, an application programming
interface (API) 1445, and an application program (or an
application) 1447. At least some of the kernel 1441, the middleware
1443, or the API 1445 may be referred to as an operating system
(OS).
[0134] The kernel 1441 may control or manage system resources
(e.g., the bus 1410, the processor 1420, and the memory 1430) that
are used to execute operations or functions implemented in the
other programs (e.g., the middleware 1443, the API 1445, or the
applications 1447). The kernel 1441 may provide an interface
through which the middleware 1443, the API 1445, or the
applications 1447 access individual components of the electronic
device 1401 to control or manage the system resources.
[0135] The middleware 1443 may function as an intermediary for the
API 1445 or the applications 1447 to communicate with the kernel
1441.
[0136] The middleware 1443 may process one or more work requests
received from the application programs 1447, according to their
priorities. For example, the middleware 1443 may give a priority,
by which a system resource (e.g., the bus 1410, the processor 1420,
or the memory 1430) of the electronic device 1401 may be used, to
at least one of the application programs 1447. For example, the
middleware 1443 may perform scheduling or load balancing for the
one or more work requests by processing the one or more work
requests according to the priority given to the at least one of the
application programs 1047.
[0137] The API 1445 is an interface used by the application 1447 to
control a function provided by the kernel 1441 or the middleware
1443, and may include at least one interface or function (e.g., an
instruction), for example, for file control, window control, image
processing, and text control.
[0138] The input/output interface 1450 may function as an interface
that may transfer a command or data that are input from the user or
another external device to another element (other elements) of the
electronic device 1401. The input/output interface 1450 may output
commands or data received from another component(s) of the
electronic device 1401 to the user or anther external device.
[0139] The display 1460 may include an LCD, an LED display, an OLED
display, a microelectromechanical system (MEMS) display, or an
electronic paper display. The display 1460 may display various
contents (e.g., a text, an image, a video, an icon, and a symbol).
The display 1460 may include a touch screen and receive, for
example, a touch, a gesture, a proximity, or a hovering input using
an electronic pen or the user's body.
[0140] The communication interface 1470 may set a communication
between the electronic device 1401 and the external electronic
device 1402, the second external electronic device 1404, or the
server 1406. For example, the communication interface 1470 may be
connected to a network 1462 through a wireless communication or a
wired communication to communicate with the second external
electronic device 1404 or the server 1406.
[0141] The wireless communication is a cellular communication
protocol, and may use at least one of long-term evolution (LTE),
LTE-advanced (ATE-A), code division multiple access (CDMA),
wideband CDMA (WCDMA), a universal mobile telecommunications system
(UMTS), wireless broadband (WiBro), or a global system for mobile
communications (GSM). Further, the wireless communication may
include a short range communication 1464. The short range
communication 1464 may include at least one of wireless fidelity
(Wi-Fi), Bluetooth, near field communication (NFC), magnetic stripe
transmission (MST), or a global navigation satellite system
(GNSS).
[0142] An MST may generate a pulse according to transmission data
by using an electromagnetic signal, and the pulse may generate a
magnetic field signal. The electronic device 1401 may transmit the
magnetic field signal to a point of sales (POS), detect the
magnetic field signal by using an MST reader, and restore the data
by converting the detected magnetic signal into an electrical
signal.
[0143] The GNSS may include at least one of, for example, a global
positioning system (GPS), a global navigation satellite system
(Glonass), a Beidou navigation satellite system (hereinafter,
"Beidou"), or the European global satellite-based navigation system
(or Galileo), according to an in-use area or a bandwidth. The wired
communication may include at least one of, for example, a universal
serial bus (USB), a high definition multimedia interface (HDMI),
recommended standard-232 (RS232), and a plain old telephone Service
(POTS). The network 1462 may include at least one of communication
networks, for example, a computer network (e.g. a LAN or a WAN),
the Internet, or a telephone network.
[0144] The electronic devices 1402 and 1404 may be of the type that
is the same as or different from that of the electronic device
1401. The server 1406 may include a group of one or more
servers.
[0145] All or some of the operations executed by the electronic
device 1401 may be executed by the electronic device 1402, the
electronic device 1404, or the server 1406. For example, when the
electronic device 1401 should execute some functions or services
automatically or upon request, it may request at least some
functions associated with the functions or services from the
electronic device 1402, the electronic device 1404, and/or the
server 1406, in place of or in addition to directly executing the
functions or services. The other electronic device(s) may execute a
requested function or an additional function, and may deliver the
result to the electronic device 1401. The electronic device 1401
may process the received result directly or additionally, and may
provide a requested function or service. To this end, for example,
the cloud computing, distributed computing, or client-server
computing technologies may be used.
[0146] Herein, the term "module" may indicate a unit including one
of hardware, software, firmware, or a combination thereof. A module
may be interchangeably used with a unit, a logic, a logical block,
a component, or a circuit. A module may be a minimum unit or a part
of an integrally configured part. A module may be a minimum unit or
a part which performs one or more functions. A module may be
implemented mechanically or electromagnetically. For example, a
module may include at least one of an application-specific
integrated circuit (ASIC) chip, a field-programmable gate array, or
a programmable-logic device, which has been known, will be
developed in the future, or performs certain operations.
[0147] At least some of the devices (e.g., modules or functions) or
methods (e.g., operations) according to various embodiments may be

optical medium (e.g., a compact disk read only memory (CD-ROM)), a
digital versatile disk (DVD), a magneto-optical medium (e.g., a
floptical disk), and a hardware device (e.g., a read only memory
(ROM), a random access memory (RAM), or a flash memory). Further,
the program instruction may include high-level language codes which
may be executed by a computer using an interpreter as well as
machine languages created by using a compiler. The above-mentioned
hardware device may be configured to be operated as one or more
software module to perform operations of various embodiments, and
the converse is applied.
[0149] The module or program module according to various
embodiments may include at least one of the above-mentioned
elements, omit some of them, or further include other elements. The
module, the program module, or the operations performed by other is
elements according to various embodiments may be performed in a
